Now imagine I ask a question and in the tags list I type
But what would be cool is if it resulted in a question tagged com-interop
Does this matter? I think it does. I'm trying to solve a com interop problem today and the huge quantity of com interop questions out there are making me mental. That is not a correct tagging. If a question is tagged both com and interop it's because it's about COM Interop and the OP didn't know about the com-interop tag. This means that my searches are much harder than they need to be. I recall we've had a lot of retagging posses looking for tags like 2010 and 7, created when people tried to type entire product names including version suffixes.
If anyone can think of an X and a Y that meet these conditions:
- X, Y, and X-Y are tags already
- a question tagged X and Y should not be tagged X-Y
- a person might be interested in X or Y, but never in X-Y so this retagging would cause them to miss it
Then by all means add those as an answer. It's my contention that no such combination exists
